Abstract

Infrared ray absorbing particles include a complex oxide. The complex oxide includes: an A1 element that is at least one element selected from the group consisting of H and alkali metals; an A2 element that is at least one element selected from the group consisting of Mg and alkaline earth metals; and a B element that is at least one element selected from the group consisting of V, Nb, and Ta. When x1 is an amount of substance of the A1 element included in the complex oxide, x2 is an amount of substance of the A2 element included in the complex oxide, and y is an amount of substance of the B element included in the complex oxide, x1, x2, and y satisfy relationships of 0.002≤(x1+x2)/y≤1.5, 0.001≤x1/y≤1, and 0.001≤x2/y≤1.
